Abstract

PURPOSE: To enable the load performance of a turbine bypass valve single body to be held of beforehand by permitting the vapour pressure in actual case which operates to a turbine bypass valve to be applied to a turbine bypass valve without using the vapour flow amount.
CONSTITUTION: In a turbine bypass valve 2 which is installed in a main vapour passage 1 which connects a reactor with a main vapour reducing valve, an oil hydraulic cylinder 17 which applies a force equal to the actual vapour force to said valve 2 is arranged in opposition to the opening and closing operation oil-hydraulic actuator 4 of said valve 2, and the oil chambers 17a and 17b on both sides of the piston 18 of the oil hydraulic cylinder 17 are connected. In said connecting conduit, a sequence valve 21 which keeps the pressure in the oil chamber 17b constant, a servo valve 26 which controls the pressure in the oil chamber 17a to follow to the vapour pressure which corresponds to the opening and closing amount of the turbine bypass valve 2 which is prescribed beforehand, and a control means consisting of a load detector 30, function generator 31, and an adder 32 are equipped with.
